PARTITION SECURING CLAMP Filed March 25, 1936 Patented Oct. 25, 1938 UNITED STATES PARTITION SECURING CLAMP Mindy Sigurdson, Winnipeg, Manitoba, Canada Application March 25, 1936, Serial No. 70,787 In Canada February 28, 1936 1 Claim.

My invention relates to improvements in a clamping device for attaching movable partitions to the sides of railway stock cars, thus doing away with the necessity of fastening such partitions with nails, bolts, or other attaching means, which may have a tendency to damage such cars and necessitate frequent repairs.

The object of my invention is, first, a clamping device, composed of two members, a clamping member, and a vertical adjustment member, capable of being attached to a partition with bolts and to the slats in the sides of a stock car by a clamp; and second, a vertical adjustment and a horizontal adjustment for different heights of slats in the sides of the car, and different widths of cars, in such a manner that the only tool needed to place a partition in a stock car is an ordinary wrench, when said partition is equipped with my device.

I attain these objects by the mechanism illustrated in the accompanying drawing, in which:

Figure 1 shows a view of the improved clamp and vertical adjustment bar.

Figure 2 is a detail view of the vertical adjustment bar on which the clamp member moves.

Figure 3 is a plan view of the clamp member showing position of the oval shaped horizontal adjustment hole through which the vertical adjustment bar is fitted; and showing by dotted lines the position of the various components of the clamp.

Figure 4 is a view of four such clamping members with vertical adjustment bars in position on a partition in place in a railway stock car.

Similar numerals refer to similar parts throughout the several views.

I represents the clamping member, being composed of a rigid, metal, F shaped structure, having an elliptical opening for the purpose of horizontal adjustment 2, at one end thereof, and two flanges, 3 and 4, at the other end, shaped to fit through the spaces 5 between the slats 6 forming the sides of a railway stock car, and capable of vertical adjustment with relation to the partition by means of the clamping member I sliding down along the vertical adjustment bar I through the elliptical opening 2 at the inner end of the clamping member I. The flange 3 of the said clamping member I is fitted with a screw-bolt 8, threaded through the opening ID in the said flange 3, and having at one end thereof a clamping face 9, and

a bolt head II at its inner end. The said screwbolt 8 is fitted with a locknut I5 which may be tightened up against the flange 3 so that the clamp will not tend to become loose from vibration. The adjustment bar I is bolted to the partition I2 by two nuts I3, and is held away from the said partition I2 by spacing nuts I4, thus allowing clamping member I to slide on said vertical adjustment bar 1. Four of such clamping members I and vertical adjustment bars I are shown attached to a partition I2 in position in a railway stock car in Figure 4.

In operation, four adjustment bars I with clamping members I are attached at suitable heights on the partition I2 placed in position in a railway stock car, and clamping members I are adjusted for height on the vertical adjustment bar I, and inserted in the spaces between the slats 5 at the sides of the said railway stock car, being fitted down over the said slats 6. The screwbolt 8 is then tightened with a wrench so that the clamping face 9 of the screw-bolt 8 is firmly brought into contact with the inside faces of the slats 6, the outside faces of the slats 6 being forced against the inside faces of the flanges 4, and by this means the partition is held in position.

I am aware that prior to my invention various means have been employed to retain partitions in position in railway stock cars, I therefore do not claim such a device broadly; but what I do claim as my invention, and desire to secure by Letters Patent is:?

In a securing device for retaining a partition in position between the Walls of a railway stock car wherein the partition has a passage therein, a clamp comprising an elongated anchoring bracket secured to thee partition frame, a rigid, F-shaped member slidably carried by said'bracket, the leg of the member having a laterally adjustable connection therewith, the head of the member being adapted to be passed through the partition passage forengaging the car wall in a direction outward from said bracket, and adjustable, clamping means carriedby the intermediate portion of the member and directed toward the head whereby the member may clamp the car wall between the head and adjustable clamping means to anchor the partition to the car wall.
